2 Claims.

This invention relates to improvements in window frames and sash of the slidable type.

In applicants Patent No. 2,182,008, issued December 5, 1939, there is disclosed a window frame construction in which the sash are readily re moved from the frame without the necessity for removing portions of the frame and in which sash weights, pulleys, and cords are eliminated. Subsequently it was found that the construction of the frame and sash could be improved which improvements are the subject of this application.

It is an object of the instant invention to de-. crease the cost of construction and installation of removable slidable sash windows.

A further object, is to simplify the installation of removable slidable sash in old window frames.

Another object is to provide window frame and sash construction of such design that either the upper or lower sash may be rotated inwardly from either jamb with the same equipment.

Other objects of the instant invention will become apparent in the course of the following specification.

In the accomplishment of these objectives, the usual strips forming the channels or slideways for sash are partially removed and in place thereof a single-unit upper channel member is attached to the top of the frame and extended downwardly on both jambs a distance substantially equal to the height of the upper sash. A

three-piece lower channel member on one J'amb coacts with the slideways provided by the upper one-piece structure to give continuous slideways on one side of the frame. The outer and the inner portions of the three-piece member are pivotally attached for inward rotation. A two- 'piece lower channel member is pivotally attached to the opposite jamb the inner piece of which also swings inwardly. In the bottom position, the lower sash is rotated inwardly by the innermost of the two-piece lower channel member. With the lower sash rotated out of the way and the upper sash slid to the lowest position, rotation of the upper sash inwardly by the outermost portion of tht three-piece lower channel member is provided. Elements of new design on the sides of the sash coacting with the slideways permits either sash to be raised or lowered to any position in a simple and effective manner. Utilizing in part the same elements, each sash is firmly held by the swingable channel members until released. The swingab le channel members have been sodesigned that simply by inverting the sam the sash can be rotated inwar y irom either jamb.

The invention will appear more clearly when taken in connection with the accompanying drawings showing by way of example a preferred embodiment of the inventive idea.

In the drawings:

Figure 1 is a front elevational view of a window with removable slidable sash and constructed in accordance with the principles of this invention.

Figure 2 is a sectional view along 2-'2 of Figure 1.

Figure 3 is a plan view taken along 3-3 of Figure 1 but on an enlarged scale.

Figure 4 is a plan view similar to Figure 3 but showing the method of removing the sash.

Figure 5 is a plan view alon 5-:5 of Figure 1.

Figure 6 is a perspective view of the rights-hand jamb shown in Figure t with the lower sash in exploded position.

Figure 7 is a sectional view along 1-! of Figure 4.

Figure 8 is a perspective view showing the lefthand jamb portion with the upper sash in 6X. ploded position.

Referring now in greater detail to the drawings where like reference numerals indicate like parts, reference numeral !0 indicates the window frame, H the upper sash, 12 the lower sash, l3 the onepiece upper channel or slideway member, 14 the three-piece lower channel member, and 15 the two-piece lower channel member.

The window frame I0 is of known type with the exception that the usual central and inner strips defining the sash channels or slideways are removed at least in part from the jambs and the top of the frame.

In place of the aforesaid strips forming the channels there is attached in the top of the frame a one-piece upper channel member i3 which, as shown in Figure 1, extends across the bottom of the frame at the top and thence downwardly on the left and right-hand jambs for a distance approximately equal to the height of the upper sash I I in the raised position as shown in Figure 1. .As most readily seen in Figure 2, the onepiece upper channel member I3, formed from any suitably rigid material, provides the upper part of the usual inner and outer channels, the inner channel being formed by spaced parallel central and inner strips and the outer channel being formed by an outer strip spaced parallel from the central strip. The inner edge of the upper member is turned to form a bead adjacent the inner periphery of the window frame. The inner and outer channels of the upper channel member Harealigned with channels formed by the reversible lower channel members I4 and I5 described in the following paragraphs.

The three-piece lower channel member I4 for the left-hand jamb (Figs. 3 and 5) is formed with the inner channel member I6, the outer channel member 24, and the intermediate plate 43.

The inner channel member I6 is constituted of an inner strip and an integrally formed bead or turned edge adjacent the inner periphery of the windowframe and is aligned with the turned edge of the upper member. The channel member I6 at the bottom is pivotally attached to the sill I1 by the plate I8 (Figs. 4 and 7) which is held in position by the known fasteners I9. It will be noted in Figure 7, that a pin is pivotally passed through the plate I8 in such a manner that the boss ZI on the bottom is similar to the boss 22 on the top so that the plate I8 may be used for mounting on either the left or righthand jamb. The pin 20 after being passed through the plate I8, extends upwardly in the bead or turned edge 23 formed integral with the channel members and which extends around the three sides of the frame to provide an ornamentation for the inner edge as well as part of a hinge means utilized as further shown. At the top of the inner channel member I6 is a pin (not shown) inserted in the bead and extended upwardly in the aligned left-hand bead of the downwardly extended portion of the upper channel member I3 which permits inward rotation of the inner channel member I6 as shown in Figure 4.

A vertical plate 43 (Figs. 3 and 4) is attached in the frame adjacent the inner edge of the inner channel member I6 in the closed position and is aligned with the bottom portion of the inner channel of the upper member.

The outer channel member 24 (Figs. 3 and 8) of the three-piece lower channel member I4 is constituted of the central strip 26 and an inte grally formed bottom portion aligned with the bottom portion of the outer channel of the upper member and is pivotally attached at the bottom to the sill I'I adjacent the outer edge of the previously mentioned vertical plate 43 by the pin 25 held in the bottom of the central strip 26 by a block 21. At the top, other blocks 28 and 29 carrying the pin 30 between the ends of the opposed central strips permit pivotally moving the channel member 24 inwardly after the channel member I6 and lower sash have been rotated inwardly and out of the way. As will be seen in Figure 3, the strip 26 is rounded at one corner to permit rotation. It will be noted that the integrally formed bottom portion of the outer member is turned inwardly adjacent the outer edge, the inwardly turned portion being aligned with the outer strip of the upper member.

On the right-hand jamb is the two-piece lower channel member I5 as most clearly seen in Figures 3 and 6. At the bottom, the innermost of the two-piece lower channel member I5 is pivotally attached to the sill I! in the same manner as that previously described for the inner channel member It on the opposite jamb. Of course, the plate I8 on the right is inverted from the position shown at the left in Figure 4. At the top, the upper edge of the innermost of the twopiece channel member I 5 is pivotally attached to the downwardly extending portion of the onepiece upper channel member by the pin 3I passed upwardly and downwardly in the aligned beads or turned edges 32 and across the jointure. An -L-shaped plate coacts with the innermost of the 4 two-piece channel member to form the outermost channel as illustrated in Figure 4.

While both the upper sash I I and lower sash I2 are of standard construction, similar channel plates 33 are fixed by any known means along each side which facilitates sliding and provides a means for maintaining each sash in any desired position in the frame without the usual cords, pulleys, and weights as follows: At the top of each of the metal strips 33 on each sash a spring member 34 is secured in a known manner while at the bottom a space 35 (Fig. 6) is left between the plates 33 and the wood of the sash. The tension of the spring members 34 against the channels is sufficient to support the sash in any desired position. Openings 36 in the innermost of the two-piece lower channel member I5 (Fig. 6) and similar openings in the outer portion 24 of the three piece lower channel member I4 provide a means for maintaining the upper part of the sash in the swingable channels when in the lower position while an outwardly and upwardly directed spring member 3'! engages the space 35 between the plates 33 and the wood of the sash whereby the lower portion of the sash is likewise securely held in position while being rotated. It will be'seen in Figures 6 and 8 that the openings 36 at the top are in reverse position to the similar openings at the bottom which permits interchangeability between the left and right j ambs in accordance with the desired direction of rotation of the sash. As may also be seen in Figure 8, a weather strip 42 may be fastened on the sill between the slideways for the top and bottom sash that is aligned with the central strips and in which event the spring member 31 is raised above the top of the strip 42 to allow for the rotation of the upper sash II in the manner previously described.

In operation Suppose it be desired to install the improved sash and slideways in an old window frame, all the known strips defining the channels around the frame except the outermost may be removed. Obviously, with but slight modification, only the lower portion of the central and innermost strips need be removed. The upper channel member I3 is then attached at the top of the frame by any known means in the manner shown in Fig ures 1 and 2. Next, the outer portion 24 of three-unit channel member I4 is installed with the outer turned edge 38 (Fig. 8) against the inner surface of the standard unremov'eci strip 39, and the central strip pivotally attached to the sill I! by the pin 25 as already described. At the top, a similar pin 36 pivotally connects the top of the central strip of the channel member 24 to the bottom of the aligned central strip in the side of the one piece upper central strip of the channel member I3 so that the outer channel member 24 is free to be rotated inwardly.

Then, the vertical plate 43 is attached adjacent the inner edge of the central strip 26 of the channel member 24 by any suitable fasteners 44.

Next, the lower inner channel member I6 is pivotally attached to the sill I! with the plate I8 and pivot pin 20 at the bottom while at the top, a pin (not shown) is pivotally passed in the aligned beads or turned edges of the upper and lower channel members across the jointure and so that the edge of the channel member IE will be adjacent the inner edge of the vertical plate 43 when in the closed position. Thus, byrotating the channel member I6 inwardly it will ass ne the position shownin Figure 3 whereby an inner slidevv'ay is provided for the lower sash 12 in the height of the window. When the channel member I6 is rotated inwardly as shown in Figure the lower sash is free to swing inwardly on the innermost of the two-piece lower channel member l5 as shown in the following paragraph.

On the opposite (right-hand) jamb is the twopiece channel member (Figs. 3 and 6') the innermost portion of which ispivotally attached to the sill I! by the pivot pin 40 similar to the previously described pivot pin and at the top by the pin 3i extending upwardly and downwardly in the aligned beads e2 across the jointure. Thus, the innermost of the two-piece lower channel member I5 is free to rotate inwardly assuming, of course, that the lower inner channel member 16 has been rotated out of the way.

su pose further, that it is desired to clean the outside of the glass 4| (Fig. 3) in the lower sash P2. The sash I2 is moved to the down position shown in Figure 1, and the lower inner channel member l6 rotated inwardly as shown in Figure 4. Then, the sash [2, held at the top by the coaction of the spring member 34 and the opening 36 and at the bottom by the coaction of the member 31 and the slot is free to be pivoted inwardly by the innermost of the two-piece lower channel member I5 as shown in Figure 6. In this manner, the outer surface of the glass 4| is in convenient position for cleaning without the necessity for leaning out of the window. If it be desired to remove the lower sash l2 from the channel member l5, an upward movement will release both the spring member 34 and the slot 35 from the coacting members.

In a similar manner, the upper sash II, with the lower sash I2 out of the way, may be slid to the down position shown in Figure 8. With the lower inner channel member l6 rotated inwardly as shown in Figure 4, the upper sash ll held in the outer channel member 24 in a manner similar to that already described for the lower sash may be swung inwardly about the pivot pins, the glass cleaned on the outside with ease and/or the sash removed from the channel member in a manner similar to that already described for the removal of the lower sash.

- Obviously, the upper channel member is readily fitted in position and may be made in accordance with established standards. The coacting lower channel members l4 and I5 have been designed for reversibility and may be installed on either jamb merely by turning through 180 whereupon the sash will be rotated inwardly in the reverse manner from that previously described. Thus, in the case of a double window, the inward rotation of the sash is never in interference.
